Thats a good idea! I have done some of that in my skin as well, to make it easier to setup. Currently in my skin I have options to set up ATTSPEED (Speed controlled volume) that you can turn on / off, change the volume levels at certain speeds ect. I did another screen that configures all of the iGuidance auto switch options (Turning on/off, mute on iG speak, switch time ect).
These little things make it much easier, like you said, instead of having to pull out the keyboard and edit the RR.ini.
